Alexander Wang has always loved a bash, and for his 10th anniversary collection tonight he threw himself a big one. Up front, a merch table sold his DoSomething.org tees and sweats, which benefit the organization’s youth and social change efforts. It was straight out of a rock show, a feeling that was accentuated inside the venue by the crush of celebrities who sat in the front row. Kanye West, Nicki Minaj, Lady Gaga, Josh Ostrovsky (a.k.a. “The Fat Jew”), The Weeknd, Bella Hadid, Mary J. Blige . . . the list goes on. Post-show, a curtain at the back of the runway opened to reveal a phalanx of pole dancers, who entertained the throngs until it was time for the party’s big numbers. Tinashe, Lil Wayne, and Ludacris all performed. But the night’s main act was the video that played after the models took their finale spin. An extended highlights reel, it was a long, loud, chronological look back at Wang’s first decade, from his early bows, short-haired and baby-faced at 21, all the way through last November’s H&M collab and his Fall ’15 advertising campaign.
